Mistakenly Banned for MMR Boosting?

Hi, all.

I was recently suspended for MMR Boosting. I have never had any one else on my account, in all the years that I have had this game. I sent a message to riot support, to try and resolve this issue; I received a very disingenuous and robotic response, almost the same as the message that I received in the beginning for the suspension, not including any evidence or facts about my suspension. I know that some other people have experienced the same random suspension, but I want to clarify some of the possibilities as to why, because I need access to my account to play in uLoL.

Possible Causes:

1. I recently moved, and my new address might have registered as some different player having access to my account.
2. I duo wiuth my friend a fair amount, and sometimes we go on large win streaks.

But other than these, I cannot understand any other logical explanation as to why.

My op.gg is clear evidence that I was not boosted, unless I would inefficiently pay someone to log into my account and go on a 7 game loss streak. Lastly, I have never had a significant jump in elo. My largest improvement was Post Season 4 - Season 5 where I climbed from Silver to Plat, but I have remained plat ever since. Can some Riot Support give me an answer that is genuine? Thank you!
